A roadway excavation ventilation dust removal and purification equipment

Abstract

The invention provides a roadway tunneling ventilation dust removal and purification device. The roadway tunneling ventilation dust removal and purification device comprises an air inlet mechanism, apressure increasing mechanism, a dustfall mechanism, a purification mechanism, a water injection mechanism and a base; and the air inlet mechanism is disposed at the front end position of the pressureincreasing mechanism in a penetrating mode, and the water injection mechanism is fixedly disposed above the pressure increasing mechanism. A water injection gun is arranged, a water injection rollerdrives the water injection gun to enable water to be continuously injected into a surface layer of a metal mine in the rotating period. When the water injection gun is inserted into the ore surface ofthe metal mine, a triangular drill bit can be retracted inward to slidably abut against the side surface of an injection head by using inclined surfaces on both sides of the triangular drill bit, aninjection head can be ejected so that the water in the water injection gun can be discharged through the triangular drill bit through the methods that the triangular drill bit is retracted into a vacant opening and the triangular drill bit slidably abuts against the injection head, multi-directional water injection can be realized, dust is well prevented from flying, the flying concentration of the metal mine in the tunneling process is reduced, and the roadway tunneling ventilation dust removal and purification device is suitable for the production and the use of a metal mine tunneling ventilation and dust removal device.

Description

technical field [0001] The invention relates to the technical field of metal ore purification devices, in particular to roadway ventilation, dust removal and purification equipment. Background technique [0002] At present, the dust hazard in the ore mining process has been listed as one of the five major hazards. In the process of metal ore mining, a large amount of dust pollution will be caused during the tunneling, rock drilling, blasting and slag removal of mine roadways. At the same time, dust Excessive concentrations have brought hidden dangers to the safe production of metal mines. [0003] The existing dust reduction methods mainly include water injection into the metal layer, spray dust reduction, and dust removal by the dust collector. The dust is collected by the dust collector, which is prone to technical defects such as dust accumulation and blockage for a long time, which greatly reduces the working efficiency of the dust collector. At the same time, the metal ...

Problems solved by technology

[0005] The present invention aims to solve the technical problems of long-term accumulation and clogging of dust, high flying concentration of dust, uneven water injection, easy blockage of water injectors, and low efficiency of purification and dust removal in the existing dust removal equipment for metal mines. A roadway excavation ventilation, dust removal and purification equipment. The invention is provided with a water injection roller, which can continuously inject water into the surface layer of the metal ore during the rotation of the water injection roller. When the water injection gun is inserted into the surface of the metal ore, the triangular drill bit can retract inward Use the inclined surfaces on both sides of the triangular drill to slide against the side of the spray head, so that the spray head can pop up, and then the water in the injection gun can flow out through the opening vacated by the retraction of the triangular drill and slide out of the spray head. Realize the effect of multi-directional water injection, which can well reduce the flying dust and reduce the dust flying concentration during the excavation process of metal mines
